I stumbled across an interesting issue. I added an inventory item that had a special character in it. Specifically, the TM (trademark) special character. I was able to add the part Ok and it looks like RepairShopr even strips out TM symbol once the part is entered. However, when I went to print a label, I received an error. I had to re-enter the part in without the TM symbol in order for the label to print for me correctly.
